Abstract

A clamping tool having a first jaw connected to a pull/push rod and a fixed second jaw connected to a housing which includes a handle disposed opposite the second jaw and arranged along side a grip provided on the housing. Displacement of the handle towards the grip moves the first jaw towards the second jaw and towards a clamping position in a stepwise manner while reverse movement of the rod and jaws is blocked by a detent member. Release of the detent member is provided by a release lever. The release lever can also be utilized, in conjunction with the detent member, to move the rod and first jaw in a release direction. Movement of the rod and first jaw in the clamping direction is caused by engagement of the rod by a carry-along member. The carry-along member, in turn, is engaged by an operating arm which, in turn, is engaged by the handle. The operating arm is slidably connected to the housing thereby enabling the overall length of the operating arm and handle to be varied. The operating arm engages a smooth surface of the carry-along member so that as the clamping force increases, the operating arm will move away from the rod and towards the handle thereby decreasing the over…
